Pony Trifecta Sketch Dump

These are just three pony concepts I drew up. Actually, they're more like ponified characters of mine (one of which I haven't even drawn, yet). Here, so you don't have to struggle with my terrible penmanship:

Top: Free Spirit (Ponified Yumi)
Cutie Mark: Covered by suit

Bottom Right: Candor Karasu (Ponified version of OC of the same name)
Cutie Mark: Silhouette of a crow

Bottom Left: Space Invader (Ponified version of OC I have yet to draw)
Cutie Mark: Image of an enemy from the Space Invaders video game
